不同产地和品种芝麻营养成分差异分析

Analysis of the Nutritional Composition of Sesame in Different Origins and Varieties

为分析不同产地和品种芝麻之间营养品质差异,以及营养品质之间的相关性,选取了山东省、河北省和湖南省200份芝麻样品,测定芝麻中脂肪、蛋白质、芝麻素和芝麻林素含量,并进行差异性和相关性分析。结果表明,不同芝麻品种之间蛋白质、脂肪、芝麻素和芝麻林素的平均含量分别为27.07%、52.27%、3.34 g/kg和1.48 g/kg。不同种皮颜色的芝麻营养品质略有差异,但差异不显著。山东省和河北省芝麻的蛋白质、脂肪含量显著高于湖南省芝麻(P<0.05)。河北省芝麻的芝麻素含量显著高于湖南省(P<0.05),但山东省、湖南省之间差异不显著。3个省份之间的芝麻林素含量差异不显著。蛋白质与脂肪含量间呈极显著负相关(P<0.01),芝麻素与脂肪含量间呈显著正相关,相关系数为0.145(P<0.05),这与之前的研究结果一致。芝麻素与芝麻林素含量间呈极显著正相关(P<0.01)。蛋白质、脂肪与芝麻林素之间相关性不显著。

In order to analyze the differences of nutritional quality and the correlation of nutritional quality between different origins and varieties,200 sesame samples from Shandong,Hebei and Hunan provinces were selected to determine the content of fat,protein,sesamin and sesamolin in sesame,and analyzed the differences and correlation.The results showed that the mean amounts of protein,fat,sesamin,and sesamolin were 27.07%,52.27%,3.34 g/kg,and 1.48 g/kg,respectively.The nutritional quality of sesame with different coat colors varied slightly but was not significant.The protein and fat content of sesame in Shandong province and Hebei province were significantly higher than those in Hunan province(P<0.05).The sesamin content of sesame in Hebei province was significantly higher than that in Hunan province(P<0.05),but not significantly between Shandong and Hunan province.The difference in sesamolin content between the three provinces was not significant.There was a very significant negative correlation between protein and fat content(P<0.01),and a significant positive correlation between sesamin and fat content,with a correlation coefficient of 0.145(P<0.05),which is consistent with previous studies.A significant positive correlation was found between sesamin and sesamolin content(P<0.01).The correlation between protein,fat and sesamolin was not significant.
